511 Test Pattern for the DTE

This test sends and monitors a 511 test pattern over the User Data Port interface.
The 511 monitor expects the external equipment to provide the clock for the
511 pattern on the interchange circuit CT113 – Transmit Signal Element Timing –
DTE Source (XTXC or TT) for timing the incoming pattern. Refer to
DTE Port (V.35) Connector
in Appendix E,
